Abstract： |
The invention is a method of preparing carboxyl functional cross-linked core-shell nano high molecular microsphere, using multiple organic alkene monomers and alkene monomers with carboxyl functional groups as raw materials, and preparing it by soapless emulsion or soapless suspension polymerization using water as medium; the product has a cross-linked structure inside both the core and shell, the core and shell are linked through chemical bonds, the carboxyl functional groups are grafted on the microsphere surface, and the particle size is less than 100 nm. By changing the composition of the core and shell, it obtains a nano high molecular microsphere with multiple different physico-chemical properties, and has very high freedom in selecting structure design. By the soapless polymerization means, it makes the product easy to purify and apply to various fields very strict with purity. |
